ABSTRACT:
The instant shoreline erosion-preventing bank installation comprises a vegetation supporting strengthened skin having negatively-buoyant bottom and side drop-skirts, which skirts each include an extendable reservoir of skin folded on itself accordion-like, and which skirts each include at least one weight. The side and bottom negatively-buoyant drop-skirts of the vegetation supporting strengthened skin fall as the bank is eroded by wave action, conforming the skin to the bank as it erodes in a storm, thereby preventing wash-away of the installation. Energy absorbing and flow control weighted ballasts are attached to the skin; which, among other things, control wave and wind action in a storm so as to prevent wash-off to, and erosion of, adjacent property that may be unprotected. In time, the installation of the invention is completely overgrown with vegetation, permitting the use and enjoyment of the bank protected thereby, provides long term protection from erosion and provides a wildlife habitat.
